ATTACHMENT FOR TELEPHONE-SWITCHBOARDS.

T 0 all whom 'it may concern:

Be it known that I, HARRY S. JANES, a citizen of the United States,residing at Hannibal, in the county of Marion and State of Missouri,have invented certain new and useful Improvements in Attachments forTelepho'ne-Switchboards, of which the fol- The object of the inventionis to provide an interchangeable device of novel and peculiarconstruction adapted to be used in connection with a switch-board jack,plug, socket or other similar means for holding it for purposes ofshowing various information to a switch-board attendant or operator.

A still further object of the invention is to provide an indicatingattachment for switchoards, comprising certain combination of partswhich are capable of expeditious ma-. nipulation according to therapidly changing conditions of telephone switch-board circuits, numbersor other similar elements.

With these and various other objects, advantages and improved results inview, the invention consists in an interchangeable device adapted to beused in connection with a switch-board for indicating vacant jacksdisconnects, take outs, transfers, number changed, out of town, not ringjack out of service, and other essential information relative tooperating a telephone switch-board or system, and to prevenl: theoperator placing plugs in certain ac s.

In the accompanying drawings forming part of this a plication, Figure 1is a front view of a telep lone switchboard showing the a plication ofthe invention. Fig. 2 is an e evation of the device in blank form, thedotted lines showing where the form is to be bent. Fig. 3 is aperspective view of the deviceready for use. Figs. 4 and 5 are rearelevations of modifications.

The same reference numerals denote the same parts throughout the severalviews of the drawings.

The switch-board 1, is of ordinary construction having the usualsockets, plug or jack holes 2.. The holder 3, for an indicating cardslate-or slip of paper 4, is cut or stamped from metal or other suitablematerial in one piece, it has side flanges 5 turned on the dotted lineA, and a bottom flange 6, turned Specification of Letters Patent.

on the dotted line B. T heseflanges hold the indicating card or slip inplace, which card or slip may be changed or replaced as desired withoutremoving or operating the holder.

The holder has two wings 7, formed by slitting the blank horizontallythrough the side edges inwardly and then slitting it at an angle to thehorizontal slits toward the center of the blank, then each wing is bentto form a semi-circle in cross section so that the pair of wingsconstitute an insertion stem 8, with bottom and top slots or openings 9and 10, respectively between the wings. The slots or openings 9 and 10,permit a spring action of the stem in placing and removing it withrespect to a switch-board or other device in connection with which theholder may be used. holder the wings have simply to be sprung togethersufiicient to insert them in a jack or plug hole of a board.

Referring to the modification shown in Fig. 4, the stem-wings 11, arestruck through the bottom and top of the plate 12, and project from itsrear face.

' In the modification shown in Fig. 5, the stem is formed by a series ofwings 13, out or stamped out of the plate 14.

The simplicity in construction and utility of these various holders isapparent, and while I have shown several variations in the construction,the same may be further varied and the size sha e and material may bechanged without eparting from the spirit of the invention as defined bythe appended claim.

Having thus described my invention what I claim as new and desire tosecure by Letters Patent is:

The combination, with an indicator board having holes, of a card holdingdevice cornprising a plate having card-holding flanges on one sidethereof, and a s ring stem composed of a plurality of flexib e prongscut out of the plate and projecting perpendicular therefrom on theopposite side of the plate and adapted to fit the said holes.

In testimony whereof I affix my signature in presence of two witnesses.
